Embodiment 1

[0051] Embodiment 1: as attached figure 1 , 2 , 4, and 5, the automatic generation method of the substation electronic point table includes the following steps:

[0052] Step 1: Retrieve the remote signaling data, telemetry data and remote control data of a certain substation from the database, and store them separately;

[0053]Step 2: traverse the remote signaling data, and extract the interval name, signal type, and alarm level from the signal description;

[0054] Interval name extraction: Create a set of regular expressions corresponding to each type of interval name, match the signal description with the regular expression, and extract and assign the interval name in response to the successful match between the signal description and the regular expression;

[0055] Signal type extraction: Create a set of regular expressions corresponding to each type of signal type, match the signal description with the regular expression, and extract and assign the signal type in res...

Embodiment 2

[0105] Embodiment 2: as attached figure 1 , 2 , 3, 4, 5, 6, and 7, the automatic generation system of a substation electronic point table includes a data retrieval module, a point table data extraction module, a point table generation module and a data storage module;

Abstract

The invention relates to the technical field of power system automation, which is a method and a system for automatically generating an electronic point table of a substation. The former comprises thefollowing steps: first, retrieving remote signal data, telemetry data and remote control data of a certain substation from a database and storing them separately; 2, traversing the telematics data, extract the interval name, the signal type and the alarm level from the signal description; 3, traversing the telemetry data and extracting the interval name from the signal description; 4, traversingthe remote control data and extracts the interval name from the signal description. The invention realizes the intelligent and automatic generation of the transformer substation point table, the resulting dot table is well-formed, the complete and correct information eliminates the manual input process of operation and maintenance personnel, avoids the input error caused by human error, greatly reduces the operation and maintenance workload of power network model, reduces the labor intensity of operation and maintenance personnel, and the correct rate of generating point table can reach more than 95%, which greatly improves the efficiency of generating point table.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, and relates to a method and system for automatically generating an electronic point table of a substation. Background technique [0002] Dispatch automation system is one of the fastest-growing technical fields in the current power system. It mainly realizes power system data collection and monitoring, power system economic operation and dispatch, power market-oriented operation and reliability, power plant operation decision support and substation integration. Automation and other functions, most of the existing dispatching automation systems are power system D5000. [0003] With the rapid development of my country's integrated and interconnected large power grid and the deepening application of unattended substations, higher requirements are put forward for power grid dispatching control technology. Substation status monitoring and remote control operation, as importan...
